ISRO Completes Development Of SSLV With Another Successful Launch, Set To Transfer Tech To Private Industry

The Indian Space Research Organisation (ISRO) on Friday (16 August) successfully completed the third and final development flight of the Small Satellite Launch Vehicle (PSLV).

The Indian space agency will now transfer the technology to the Indian private industry and the state-run NewSpace India Limited (NSIL).

In a statement, ISRO said that the third developmental flight of SSLV (SSLV-D3) was successful as the SSLV-D3 placed an Earth Observation Satellite, EOS-08, precisely into the orbit.

"This marks the successful completion of ISRO/DOS's SSLV Development Project," the space agency said.

"With technology transfer, the Indian industry and the NSIL will now produce SSLV for commercial missions," ISRO added.

The SSLV is capable of launching mini, micro or nano satellites (10 to 500kg mass) into 500 km planar orbit.

SSLV is a three-stage launch vehicle with all solid propulsion stages and liquid propulsion based Velocity Trimming Module (VTM) as terminal stage.

According to ISRO, the design drivers of SSLV are low cost, low turn-around time, flexibility in accommodating multiple satellites, launch on demand feasibility, and minimal launch infrastructure requirements etc.

Meanwhile, the EOS-08 is a first-of-its-kind mission built on a standard ISRO’s Microsat/IMS-1 bus with a suite of advanced payloads for observation in IR range, novel GNSS-R Payload and SiC UV dosimeter.

The satellite carries a host of new technology developments in satellite mainframe systems like an Integrated Avionics system - Communication, Baseband, Storage and Positioning (CBSP) Package, Structural panel embedded with PCB, embedded battery, Micro-DGA (Dual Gimbal Antenna), M-PAA (Phased array antenna) and Flexible solar panel & Nano star sensor etc for onboard Technology Demonstration.

The NSIL, which was setup in 2019, is the a public sector undertaking under the Department of Space and is responsible for producing, assembling and integrating the launch vehicle with the help of industry consortium.

The main objective of NSIL is to scale up private sector participation in Indian space programmes.
